Class EcdhWithX963KdfParamSpec

java.lang.Object

com.amazonaws.cloudhsm.jce.provider.spec.EcdhWithX963KdfParamSpec

All Implemented Interfaces:

java.security.spec.AlgorithmParameterSpec

public class EcdhWithX963KdfParamSpec
extends java.lang.Object
implements java.security.spec.AlgorithmParameterSpec

EcdhWithX963KdfParamSpec implements AlgorithmParameterSpec for specifying parameters for ECDH key agreement with X9.63 Key Derivation Function (KDF).

This class provides the necessary parameters for deriving keys using the X9.63 KDF scheme with ECDH key agreement. It allows specification of shared information and key attributes that will be used during the key derivation process.

The key attributes specify the characteristics of the derived key, while the shared information provides additional data that will be incorporated into the key derivation.

Constructor Detail

EcdhWithX963KdfParamSpec

public EcdhWithX963KdfParamSpec(byte[] sharedInfo,
                                KeyAttributesMap keyAttributes)
                         throws java.security.InvalidParameterException

Constructs a new instance with the specified shared information and key attributes.

Parameters:

sharedInfo - Additional shared information for key derivation

keyAttributes - Attributes for the derived key

Throws:

java.security.InvalidParameterException - when keyAttributes is null, when keyAttributes does not contain a SIZE attribute, or when sharedInfo is null or empty. These validations ensure proper key derivation parameters are provided.
